Curious if anyone here has ever taken the rear swing arm off a Giant ATX Team or ATX-One before ?

I bought one a while ago and the chainstays are cracked quite bad, one just popped up on ebay and I bought it after looking at it first and its rear end being fine.

Ive managed to get most of it off except the part I need (typical) the drive side pilot cover and bolt came out fine, but the non drive side just turns and you can see main pivot/axel spinning too. I can kinda see a the smallest torxkey hole up there also but thats just part of the cover bolt.

I cant find anything on the net and I really need this to come out/off, or ill just have to cut the frame or pivot in half to be able to get to it.

any help would be great
